DETAILED DESCRIPTION

The subject disclosure describes, among other things, illustrative embodiments for selecting a format in which an item of media content is to be presented at a client device communicating over a network, based on a list, generated by the client device, of appropriate formats for the media content. Other embodiments are described in the subject disclosure.

One or more aspects of the subject disclosure include a method comprising sending, by a processing system including a processor of a media service provider, a first list of formats associated with a media content item to a client device; the media service provider communicates with the client device over a network. The method also comprises receiving from the client device a selection of a format for presentation of the media content item; the selected format comprises an entry in a second list of formats generated by the client device in accordance with filtering of the first list of formats by the client device using filtering criteria. The filtering criteria are based at least in part on performance metrics of the network, a user profile, capabilities of the client device, a physical environment of the client device, or a combination thereof. The method further comprises transmitting the media content item in the selected format to the client device and, during the presentation of the media content item, dynamically altering transmission of the media content item to the client device in response to an indication from the client device that the presentation be continued in a new format different from the selected format.

One or more aspects of the subject disclosure include a device comprising a processing system including a processor of a media service provider, and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations. The operations comprise sending a first list of formats associated with a media content item to a client device; the media service provider communicates with the client device over a network. The operations also comprise receiving from the client device a selection of a format for presentation of the media content item; the selected format comprises an entry in a second list of formats generated by the client device in accordance with filtering of the first list of formats by the client device using filtering criteria. The filtering criteria are based at least in part on performance metrics of the network, a user profile, capabilities of the client device, a physical environment of the client device, or a combination thereof. The operations further comprise receiving a notice from the client device identifying a default format different from the selected format, and transmitting the media content item in the selected format to the client device. The operations also comprise dynamically altering transmission of the media content item to the client device during the presentation of the media content item, in response to an indication from the client device that the presentation be continued in a new format different from the selected format.

One or more aspects of the subject disclosure include a non-transitory machine-readable medium comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations. The operations comprise sending a first list of formats associated with a media content item to a client device via a network, and receiving from the client device a selection of a format for presentation of the media content item. The selected format comprises an entry in a second list of formats generated by the client device, in accordance with filtering of the first list of formats by the client device using filtering criteria. The filtering criteria are based at least in part on performance metrics of the network, a user profile, capabilities of the client device, a physical environment of the client device, or a combination thereof. The operations also comprise transmitting the media content item in the selected format to the client device and, during the presentation of the media content item, dynamically altering transmission of the media content item to the client device in response to an indication from the client device that the presentation be continued in a new format different from the selected format.

FIG. 1 schematically illustrates an embodiment 100 of the disclosure, in which a media service provider and a client device communicate over a network, and in which the client device selects a format for media content to be presented at the client device. In this embodiment, the media service provider can include a media streaming server 120 delivering media content 101 to the client device over network 150. Media content 101 is provided by a content provider system 110; in this embodiment, the content provider system 110 and the media streaming server 120 are different entities.

The media streaming server 120 maintains a list 122 of all the formats in which the content 101 can be presented. In general, the same item of content may be provided to the client device in any of multiple formats; the content may thus be available from streaming server 120 in multiple variants, each in a different format. List 122 may be viewed as an unfiltered list that includes all formats for the content 101 that exist on server 120.

When the client device 163 (operating in a client environment 160 and communicating with the service provider over network 150) requests content 101, the media streaming server 120 responds by sending the unfiltered format list 122 to the client device 163. Client device 163 then stores list 122 in a local storage device (not shown in FIG. 1).

The client device performs a filtering procedure to determine whether a format is appropriate for presentation of the content. In this embodiment, client device 163 is aware of network conditions, and can filter list 122 using criteria 141. Criteria 141 can include characteristics of the network 150 on which the client device operates, including network metrics (e.g. network traffic, available bandwidth), and a subscriber data plan associated with the client device. More generally, criteria 141 include criteria that are network-related but device-independent; that is, criteria 141 are independent of the configuration or capabilities of the client device.

The filtering procedure at the client device also includes filtering using device-related criteria 161. Criteria 161 can include features and configurations of client devices (in this embodiment, device 163 with various devices possibly connected thereto), features of the physical environment in which the device operates, codecs supported by the device, user preferences, etc. For instance, any format that has a spatial video resolution exceeding that of the device screen can be deemed inappropriate. As another instance, if the video is encoded in a format that the device does not support, it will again be deemed as inappropriate.

Based on the filtering using criteria 141-161, the client device 163 generates a customized list 162 of formats that are compatible with the client device. List 162 includes all of the formats for content 101 that are deemed appropriate by the client device for the current configuration and environment of the client device. In the filtering procedure, this determination is made for each entry on list 122; each entry may be viewed as a variant of the content in the listed format.

The client device selects a format for presentation of the content from list 162, and transmits the selection 171 to the streaming server 120. The client device can then obtain the content in the selected format.

In another embodiment, the client device 163 can also select a default format from list 162 for receiving the content 101, and transmit this selection to the streaming server 120. The default format can be used to provide the content if a fault occurs in transmitting the content in the selected format. The default format can be used until the client device makes another selection.

Some additional examples of criteria 161 that can be applied in generating the customized format list 162 are as follows:

(a) Data usage, according to the type of network (for example, cellular vs. Wi-Fi) and data plan (for example, capped vs. uncapped): The client may decide to not include high bit-rate variants in list 162 if, for example, the client is on a cellular network and has a data cap, even if the client is able to play back those high bit-rate variants.

(b) Type of display device: The client device can be a smartphone or tablet that uses its own display, or alternatively be connected to a much larger display (for example, a 4K television) with greater capabilities.

(c) Display device capabilities: The display device capabilities can impact display resolution, display dynamic range (for example, High Dynamic Range vs. Standard Dynamic Range), and display color gamut (for example, a wide color gamut vs. a standard color gamut). If, for example, content is to be presented on a smartphone with a small screen, HD resolution, and standard dynamic range, operating according to ITU-R Recommendation BT.709 (Rec709), list 162 may include one set of formats, but if the smartphone is connected to a 4K, high dynamic range television operating according to ITU-R Recommendation BT.2020 (Rec 2020), list 162 may include a different set of formats.

(d) Type of audio output device: The client device (e.g. television or smartphone) may use its own speakers; alternatively, the client device may be connected to a surround sound system or to headphones capable of rendering immersive audio.

(e) Supported coding schemes: Some variants may be encoded using older standards (such as MPEG-2 video and Mp3 audio) while other variants may be encoded using newer standards such as HEVC or E-AC3. In an embodiment, the client device may not itself support the newer codecs, but when connected to a smart TV may be able to pass through those variants using the newer codec to the smart TV.

(f) Battery status: In another embodiment, a smartphone may support the newer codecs but, because its battery resources are limited, will use the older codecs which use fewer CPU cycles (for example, when on a Wi-Fi network with adequate bandwidth). In a further embodiment, the client device may use lower resolution and/or lower bit-rate variants to save battery power.

(g) Content provider fees/charges: A content provider may charge a premium for the 4K version and/or the HDR version of the content. If so, the user may not want to pay the higher fees, and filter the variants accordingly.

(h) Physical environment: In addition to its environment regarding device type, network connectivity, and/or network usage, the client can be aware of its physical environment (e.g. light level, noise level, etc.) and construct a customized format list for delivering the content in that environment.

FIG. 2 schematically illustrates a system 200 in which a content format is dynamically altered, in accordance with embodiments of the disclosure. As shown in FIG. 2, the client device environment 160 includes several different devices (desktop computer 163, smartphone 165, headphones 166, television 168) that can be connected in various configurations. In this embodiment, streaming server 120 provides content 201, in a format 202 previously selected by the client, to smartphone 165.

If the client environment changes during the presentation (for example, the client is a mobile device moving into an area covered by a different network, the user connects headphones 166 to the smartphone 165, the battery of smartphone 165 is re-charged, etc.), the client can generate a new customized format list 212 by re-filtering the stored format list 122. The client can then select a new format for the content, and send the service provider a message 211 that the presentation of the content is to be continued in the new format 221. In this embodiment, the client may also select a new default format, in addition to selecting a new format for continuing the presentation.

It will be appreciated that in embodiments of the disclosure, content can be delivered by adaptive streaming applications in a format selected by the client, where the client is network-aware as well as aware of its own capabilities. Furthermore, the list of appropriate formats can be dynamically changed during presentation of the content.

FIG. 3 is a timing chart depicting an illustrative embodiment of content presentation with dynamically changing formats. As shown in FIG. 3, content to be presented by the client (e.g. content 201 in FIG. 2) is segmented into chunks, with each chunk having a duration typically 4-10 seconds. The chunk boundaries are aligned across all formats, thereby providing switching points between formats as the client environment 160 varies and the client accordingly sends new alert messages 211 during the presentation.

In this embodiment, the content is initially presented using format 310; chunks 311-313 are delivered, ending at times T₁-T₃ respectively. An event occurs at time 351 (e.g. a bandwidth change), in response to which the client selects a new format 320. When delivery of the current chunk 313 concludes, the presentation continues with the new format 320. Chunks 321-322 are delivered in this format, ending at times T₄, T₅ respectively. Another event occurs at time 352 (e.g. a change in device configuration), in response to which the client selects a new format 330. When delivery of the current chunk 322 concludes, the presentation continues with the new format 330. Chunks 331-333 are delivered in this format, ending at times T₆-T₈ respectively. An additional event occurs at time 353 (e.g. a change in physical environment), in response to which the client selects a new format 340. Chunks in format 340 are delivered beginning at time T₈.

FIGS. 4-5 are connected flowcharts depicting an illustrative embodiment of a method used by systems 100-200. In response to a request 401 from the client, the streaming server associated with the media service provider sends an unfiltered list of formats to the media service provider (step 402); this list includes all formats in which the content exists on the streaming server. The client stores the unfiltered list (step 404) at a storage device local to the client device.

The client device performs a filtering procedure using network-related and device-related criteria (step 406) to generate a list of formats customized for the client (step 408). The client stores the customized list (step 410). In this embodiment, the client device also identifies a default format for providing the content (step 412).

The client device then transmits a selection of a format from the customized list to the media streaming server (step 414). The media streaming server proceeds to transmit the content in the selected format to the client device (step 416).

The content presentation 501 by the client device comprises a series of chunks in the selected format, transmitted by the media streaming server. If a fault occurs in the transmission of the content (step 502), the media streaming server can switch to the default format and continue with the presentation in that format (step 504). Otherwise, the presentation continues in the selected format. During the presentation, if a change occurs (step 506) in the client environment (e.g. a bandwidth or network change, a change in client device configuration, a change in physical environment, etc.), the client device can select a new format and transmit a message to the media streaming server, alerting the media streaming server of that selection (step 508). The media streaming server then continues to transmit chunks of content in the new format (step 510). If a new format is not selected, the media streaming server continues to transmit chunks in the existing format, which may be the default format (step 512).

In an embodiment, the default format is used only until the client selects another format (step 505). The client then transmits a message to the media streaming server, alerting the media streaming server of that selection. Presentation in the selected alternate format can then begin with the next chunk 513.

While for purposes of simplicity of explanation, the respective processes are shown and described as a series of blocks in FIGS. 4-5, it is to be understood and appreciated that the claimed subject matter is not limited by the order of the blocks, as some blocks may occur in different orders and/or concurrently with other blocks from what is depicted and described herein. Moreover, not all illustrated blocks may be required to implement the methods described herein.

FIG. 6 depicts an illustrative embodiment of a communication system 600 for providing various communication services, such as delivering media content. The communication system 600 can represent an interactive media network, such as an interactive television system (e.g., an Internet Protocol Television (IPTV) media system). Communication system 600 can be overlaid or operably coupled with systems 100-200 of FIGS. 1 and/or 2 as another representative embodiment of communication system 600. For instance, one or more devices illustrated in the communication system 600 of FIG. 6 can comprise a processing system including a processor of a media service provider, and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations. The operations can comprise sending a first list of formats associated with a media content item to a client device that communicates with the media service provider device over a network. The operations can also comprise receiving from the client device a selection of a format for presentation of the media content item; the selected format can comprise an entry in a second list of formats generated by the client device in accordance with filtering of the first list of formats by the client device using filtering criteria. The filtering criteria can be based at least in part on performance metrics of the network, a user profile, capabilities of the client device, a physical environment of the client device, or a combination thereof. The operations can further comprise receiving a notice from the client device identifying a default format different from the selected format, and transmitting the media content item in the selected format to the client device. The operations can also comprise dynamically altering transmission of the media content item to the client device during the presentation of the media content item, in response to an indication from the client device that the presentation be continued in a new format different from the selected format.

In one or more embodiments, the communication system 600 can include a super head-end office (SHO) 610 with at least one super headend office server (SHS) 611 which receives media content from satellite and/or terrestrial communication systems. In the present context, media content can represent, for example, audio content, moving image content such as 2D or 3D videos, video games, virtual reality content, still image content, and combinations thereof. The SHS server 611 can forward packets associated with the media content to one or more video head-end servers (VHS) 614 via a network of video head-end offices (VHO) 612 according to a multicast communication protocol. The VHS 614 can distribute multimedia broadcast content via an access network 618 to commercial and/or residential buildings 602 housing a gateway 604 (such as a residential or commercial gateway).

The access network 618 can represent a group of digital subscriber line access multiplexers (DSLAMs) located in a central office or a service area interface that provide broadband services over fiber optical links or copper twisted pairs 619 to buildings 602. The gateway 604 can use communication technology to distribute broadcast signals to media processors 606 such as Set-Top Boxes (STBs) which in turn present broadcast channels to media devices 608 such as computers or television sets managed in some instances by a media controller 607 (such as an infrared or RF remote controller).

The gateway 604, the media processors 606, and media devices 608 can utilize tethered communication technologies (such as coaxial, powerline or phone line wiring) or can operate over a wireless access protocol such as Wireless Fidelity (WiFi), Bluetooth®, Zigbee®, or other present or next generation local or personal area wireless network technologies. By way of these interfaces, unicast communications can also be invoked between the media processors 606 and subsystems of the IPTV media system for services such as video-on-demand (VoD), browsing an electronic programming guide (EPG), or other infrastructure services.

A satellite broadcast television system 629 can be used in the media system of FIG. 6. The satellite broadcast television system can be overlaid, operably coupled with, or replace the IPTV system as another representative embodiment of communication system 600. In this embodiment, signals transmitted by a satellite 615 that include media content can be received by a satellite dish receiver 631 coupled to the building 602. Modulated signals received by the satellite dish receiver 631 can be transferred to the media processors 606 for demodulating, decoding, encoding, and/or distributing broadcast channels to the media devices 608. The media processors 606 can be equipped with a broadband port to an Internet Service Provider (ISP) network 632 to enable interactive services such as VoD and EPG as described above.

In yet another embodiment, an analog or digital cable broadcast distribution system such as cable TV system 633 can be overlaid, operably coupled with, or replace the IPTV system and/or the satellite TV system as another representative embodiment of communication system 600. In this embodiment, the cable TV system 633 can also provide Internet, telephony, and interactive media services. System 600 enables various types of interactive television and/or services including IPTV, cable and/or satellite.

The subject disclosure can apply to other present or next generation over-the-air and/or landline media content services system.

Some of the network elements of the IPTV media system can be coupled to one or more computing devices 630, a portion of which can operate as a web server for providing web portal services over the ISP network 632 to wireline media devices 608 or wireless communication devices 616.

Communication system 600 can also provide for all or a portion of the computing devices 630 to function as a server (herein referred to as server 630). The server 630 can use computing and communication technology to perform filtering of the lists of media content presentation formats, which can include, among other things, the techniques in methods 400-500 of FIGS. 4-5. For instance, functions of server 630 can be similar to the functions described for media streaming server 120 of FIG. 1 in accordance with methods 400-500. The media processors 606 and wireless communication devices 616 can be provisioned with software functions to utilize the services of server 630. For instance, functions of media processors 606 and wireless communication devices 616 can be similar to the functions described <for the communication devices 165 of FIG. 2 in accordance with methods 400-500.

Multiple forms of media services can be offered to media devices over landline technologies such as those described above. Additionally, media services can be offered to media devices by way of a wireless access base station 617 operating according to common wireless access protocols such as Global System for Mobile or GSM, Code Division Multiple Access or CDMA, Time Division Multiple Access or TDMA, Universal Mobile Telecommunications or UMTS, World interoperability for Microwave or WiMAX, Software Defined Radio or SDR, Long Term Evolution or LTE, and so on. Other present and next generation wide area wireless access network technologies can be used in one or more embodiments of the subject disclosure.

FIG. 7 depicts an illustrative embodiment of a communication system 700 employing an IP Multimedia Subsystem (IMS) network architecture to facilitate the combined services of circuit-switched and packet-switched systems. Communication system 700 can be overlaid or operably coupled with systems 100-200 of FIGS. 1 and/or 2 and communication system 600 as another representative embodiment of communication system 600. In particular, communication system 600 can be configured to perform a method comprising sending, by a processing system including a processor of a media service provider, a first list of formats associated with a media content item to a client device, where the media service provider communicates with the client device over a network. The method can also comprise receiving from the client device a selection of a format for presentation of the media content item; the selected format can comprise an entry in a second list of formats generated by the client device in accordance with filtering of the first list of formats by the client device using filtering criteria. The filtering criteria can be based at least in part on performance metrics of the network, a user profile, capabilities of the client device, a physical environment of the client device, or a combination thereof. The method can further comprise transmitting the media content item in the selected format to the client device and, during the presentation of the media content item, dynamically altering transmission of the media content item to the client device in response to an indication from the client device that the presentation be continued in a new format different from the selected format.

Communication system 700 can comprise a Home Subscriber Server (HSS) 740, a tElephone NUmber Mapping (ENUM) server 730, and other network elements of an IMS network 750. The IMS network 750 can establish communications between IMS-compliant communication devices (CDs) 701, 702, Public Switched Telephone Network (PSTN) CDs 703, 705, and combinations thereof by way of a Media Gateway Control Function (MGCF) 720 coupled to a PSTN network 760. The MGCF 720 need not be used when a communication session involves IMS CD to IMS CD communications. A communication session involving at least one PSTN CD may utilize the MGCF 720.

IMS CDs 701, 702 can register with the IMS network 750 by contacting a Proxy Call Session Control Function (P-CSCF) which communicates with an interrogating CSCF (I-CSCF), which in turn, communicates with a Serving CSCF (S-CSCF) to register the CDs with the HSS 740. To initiate a communication session between CDs, an originating IMS CD 701 can submit a Session Initiation Protocol (SIP INVITE) message to an originating P-CSCF 704 which communicates with a corresponding originating S-CSCF 706. The originating S-CSCF 706 can submit the SIP INVITE message to one or more application servers (ASs) 717 that can provide a variety of services to IMS subscribers.

For example, the application servers 717 can be used to perform originating call feature treatment functions on the calling party number received by the originating S-CSCF 706 in the SIP INVITE message. Originating treatment functions can include determining whether the calling party number has international calling services, call ID blocking, calling name blocking, 7-digit dialing, and/or is requesting special telephony features (e.g., *72 forward calls, *73 cancel call forwarding, *67 for caller ID blocking, and so on). Based on initial filter criteria (iFCs) in a subscriber profile associated with a CD, one or more application servers may be invoked to provide various call originating feature services.

Additionally, the originating S-CSCF 706 can submit queries to the ENUM system 730 to translate an E.164 telephone number in the SIP INVITE message to a SIP Uniform Resource Identifier (URI) if the terminating communication device is IMS-compliant. The SIP URI can be used by an Interrogating CSCF (I-CSCF) 707 to submit a query to the HSS 740 to identify a terminating S-CSCF 714 associated with a terminating IMS CD such as reference 702. Once identified, the I-CSCF 707 can submit the SIP INVITE message to the terminating S-CSCF 714. The terminating S-CSCF 714 can then identify a terminating P-CSCF 716 associated with the terminating CD 702. The P-CSCF 716 may then signal the CD 702 to establish Voice over Internet Protocol (VoIP) communication services, thereby enabling the calling and called parties to engage in voice and/or data communications. Based on the iFCs in the subscriber profile, one or more application servers may be invoked to provide various call terminating feature services, such as call forwarding, do not disturb, music tones, simultaneous ringing, sequential ringing, etc.

In some instances the aforementioned communication process is symmetrical. Accordingly, the terms “originating” and “terminating” in FIG. 7 may be interchangeable. It is further noted that communication system 700 can be adapted to support video conferencing. In addition, communication system 700 can be adapted to provide the IMS CDs 701, 702 with the multimedia and Internet services of communication system 600 of FIG. 6.

If the terminating communication device is instead a PSTN CD such as CD 703 or CD 705 (in instances where the cellular phone only supports circuit-switched voice communications), the ENUM system 730 can respond with an unsuccessful address resolution which can cause the originating S-CSCF 706 to forward the call to the MGCF 720 via a Breakout Gateway Control Function (BGCF) 719. The MGCF 720 can then initiate the call to the terminating PSTN CD over the PSTN network 760 to enable the calling and called parties to engage in voice and/or data communications.

It is further appreciated that the CDs of FIG. 7 can operate as wireline or wireless devices. For example, the CDs of FIG. 7 can be communicatively coupled to a cellular base station 721, a femtocell, a WiFi router, a Digital Enhanced Cordless Telecommunications (DECT) base unit, or another suitable wireless access unit to establish communications with the IMS network 750 of FIG. 7. The cellular access base station 721 can operate according to common wireless access protocols such as GSM, CDMA, TDMA, UMTS, WiMax, SDR, LTE, and so on. Other present and next generation wireless network technologies can be used by one or more embodiments of the subject disclosure. Accordingly, multiple wireline and wireless communication technologies can be used by the CDs of FIG. 7.

Cellular phones supporting LTE can support packet-switched voice and packet-switched data communications and thus may operate as IMS-compliant mobile devices. In this embodiment, the cellular base station 721 may communicate directly with the IMS network 750 as shown by the arrow connecting the cellular base station 721 and the P-CSCF 716.

Alternative forms of a CSCF can operate in a device, system, component, or other form of centralized or distributed hardware and/or software. Indeed, a respective CSCF may be embodied as a respective CSCF system having one or more computers or servers, either centralized or distributed, where each computer or server may be configured to perform or provide, in whole or in part, any method, step, or functionality described herein in accordance with a respective CSCF. Likewise, other functions, servers and computers described herein, including but not limited to, the HSS, the ENUM server, the BGCF, and the MGCF, can be embodied in a respective system having one or more computers or servers, either centralized or distributed, where each computer or server may be configured to perform or provide, in whole or in part, any method, step, or functionality described herein in accordance with a respective function, server, or computer.

The server 630 of FIG. 6 can be operably coupled to communication system 700 for purposes similar to those described above. Server 630 can provide services to the CDs 701, 702, 703 and 705 of FIG. 7, which can be adapted with software to utilize the services of the server 630. Server 630 can be an integral part of the application server(s) 717, which can be adapted to the operations of the IMS network 750.

For illustration purposes only, the terms S-CSCF, P-CSCF, I-CSCF, and so on, can be server devices, but may be referred to in the subject disclosure without the word “server.” It is also understood that any form of a CSCF server can operate in a device, system, component, or other form of centralized or distributed hardware and software.
